# DO NOT EDIT THIS SCRIPT, CREATE AND EDIT apmcontinue IN THIS DIRECTORY; you
# can put your stuff into apmcontinue for every link you create to apmscript;
# for a start and definitely enough for most laptops we have two links and
# according subroutines defined here: suspend and resume; all other links
# will be redirected directly to apmcontinue which you can create; also
# suspend and resume call apmscript, so you can also do other things (like
# reinitialising some PCMCIA-Card) there; apmcontinue will get the name
# as which it was called as $1; for debugging see the logfiles
#
# If you think something in this script needs to be changed anyway, please
# report it to http://bugzilla.redhat.com/bugzilla/
#
# This script can be controlled by editing /etc/sysconfig/apmd.
